WILHELM PAUL ZIMMERMANN, OF SOHGNEBERG, NEAR BERLIN, GERMANY.

MECHANISM FOR MANUFACTURING CHENILLE STRIPS.

To all whom "it may concern:

Be it known that I, lVnamLM PAUL ZIM- .MERMANN, of 1 Sedanstrasse,Schoneberg, near Berlin, Germany, a subject of the German Emperor, haveinvented certain new and useful Improved Mechanism for ManufacturingChenille Strips, of which the following is a specification.

Chenille used in the making of carpets, coverlets, etc. is generallyeither woven and then cut or is made on chenille-machines in the form oflittle bundles or bunches. As well as these universally known modes ofmanufacture, there is another process in use in which the threadsforming the chenille are gathered and separated into bundles by seamssewed through them. In that process the threads, which are held by twothreadguides, are cut ofi at the desired width and laid parallel one toanother between two sets of binding threads, stretched out and arrangedone above the other. They are then fed into a sewing contrivance havingany desired number of needles one alongside another, where they areseamed through and then cut into strips between the threads so that thestrips of chenille thus made show an open pile on both sides.

The subject matter of the present invention consists in improvedmechanism for use in the manufacture of chenille which mechanism alsobinds the pile threads up into bundles by means of seams. As contrastedwith the mechanism hitherto used the characteristic feature of thisinvention lies in the auxiliary means adopted for laying thepile-threads and feeding them into the sewing device. Hitherto, specialarrangements and devices have been necessary to cut off the pile-threadat a fixed width, to bring it into its exact position and then to pushit between special binding threads, but by the present invention notonly are a number of the stages in this work and the means for doingthem rendered superfluous, but fur ther, owing to the simplification ofthe operations, a more perfect form is obtained and that form isobtained with more certainty so that the threads are fed to the sewingdevice with a fixed width and in a continuous row. The result aimed atis attained by arranging the pile-threads in parallel layers on twoparallel disks, fixed alongside one another, and having pins aroundtheir circumferences arranged like the spokes of a wheel, so that aloosely stretched Specification of Letters Patent.

row or series of threads is obtained. To effect this, a hook or catcherleads the thread through between two pins on one disk and lays it arounda pin on the other disk. The threads thus laid are fed to one or moreneedles, sewed, and when the laying disks are turned farther around theyare cut into strips by cutting contrivances between the seams in thedirection in which the row of threads runs. These strips are carried bya tension regulator to an ironing cylinder, which smoothes off the endsof the threads, and they are then wound up on reels.

In the accompanying drawings :Figures 1 and 2 show the machine in sideview and front view with the thread catchers removed. Figs. 3 and 4tshow the thread changing mechanism in side view and front view. Figs. 5and 6 show a longitudinal section and an end view of the thread guideattached to the thread guide wheel, represented in Figs. 1 and 2. Fig. 5is a detail partly in section showing the thread hook or catcherremoved. Figs. 7 to 9 show, in elevation and plan, the positions of thethread hook attached to the thread-guide, as produced by turning theratchet wheel on the thread-guide, during the operations of taking up,carrying over and laying down the thread. Figs. 10 and 11 show thethread holder in front View and side view, but without mouthpiece. Inthe front View the lever springs are omitted. Figs. 12 and 13 show thedouble sewing device in longitudinal section and front view. Figs. 14and 15 show the cutting mechanism in side view and front view. Fig. 16shows a side view and an inverted plan of the steel rail on thepedestal. Fig. 17 is a plan view of the pedestal with steel rail. Fig.18 shows the position of the striking pins on the segment. Figs. 19 and20 show in front view and side view the bearing of the shaft 81 for thethread holding device for holding the end of the thread. Fig. 21 andFig. 22 show in plan view and side view the pawl and ratchet for the twolaying wheels. Figs. 23, 2 1, 25 and 26 are diagrammatic views showingdifferent positions of the parts with relation to the hoop and thecutting off device.

The various parts of the mechanism for tensioning and sewing the woolenthreads, for cutting off the pile in single threads, as well as thewhole driving gear are secured on a table 1.

The apparatus is driven from a shaft 3,

having fast and loose belt pulleys 2, the shaft being carried on thepedestals 4 and 5, each of which has three journal bearings, and also inthe bearing 6. By means of beveled wheels this shaft 3 drives the twoshafts 7 and 8 that are at right angles to shaft 3 and are carried inbearing 9 and 10 and 11 and. 12 respectively. The revolution of theshaft 7, with the aid of a cam disk and an angle lever 50, sets inmotion a thread changing contrivance 13, see Figs. 1 and 4 and by theaid of a second cam rangement it causes a roller 14 to turn as shown in:Fig. 4. By the motion of this last mentioned roller a pattern card 15,connected with the thread changing arrangement 13, is drawn off a drum16 or respectively is led to a drum 17, which drums are set in bearings18 and 19' secured to the table legs or supports. The revolution of thesecond transverse shaft 8 effects, by means of a ratchet contrivance,the turning of the two thread laying wheels 20 and 21, which are fittedwith their shaft 22 in trestle bearings 118 and 119 Fig. 13 placedbetween the l'ay ing wheels. This ratchet device, for the two layingwheels is operated by the shaft 8 and is shown in Figs. 21 and 22. Theclutch device consists of the plumber block 137, the

cam 138, the forcing lever 139, the roller 140, the pawl 141, the platespring 142, the ratchet wheel 143, the brake spring 144, the screwspindle 145 for the ratchet wheel 143, the spiral spring 146, the gearwheel 147 and a pinion wheel (not shown on the drawing) which engageswith wheel 147 and which issecured to the ratchet wheel 143-. The clutchdevice works in the following manner :-The cam 138, secured on the shaft8 (Fig. 1) is pushed forward by turning the shaft and forcing lever 139in the direction of the row 148. By this means the pawl 141 turns theratchet wheel 143 forward one tooth thereby turning the gear wheel 147,which is fixed on theshaft 22 (Fig. 1) by means of the pinion wheel (notshown on the drawing) which is connected with the ratchet wheel 143 andat the same time the laying wheels which are placed on the shaft 22 willalso be turned. After the cam 138 has passed, the spiral spring 146returns the forcing lever 139 to its original position and so theoperation continues. Further, the revolution of the shaft 8 brings intooperation a cutting off contrivance 23, which cuts the sewedpile threadslaid on to the wheels into strips, see Figs. 14 and 15; and it alsoactuates by suitable means the upper roller of a material regulatingdevice 24. In addition tothis, two eccentrics fixed on the shaft 8 putinto motion the outer and the inner mechanism of two sewing devices,which are inclined to one another at about an angle of 45 and which workupon the pile that has been stretched between the laying wheels 20 diskand a ratchet ar-' and 21. These sewing devices are fitted in means asby transmission wheels 2', 2 and 2 and connecting gears 3, 3", o and 3,see Figs. 1 and 2, the spindles of which have their hearings in thepedestals 4 and The shaft 27 carries on one end the thread guide wheel29, fittedv with thread guides 28, while on the other end it has a chainwheel 30. By means of a chain, not shown, this chain wheel causes therevolution of a shaft that is not shown in Figs. 1 and 2. This omittedshaft runs parallel with the shaft 3 and is set on the table 1 where itserves as a: counter shaft. By means of a cam drive this shaft, notshown in the drawing, actuates adevice represented in Figs. 10' and 11which serves to hold and catch up again the woolen threads forming thepile. The hooked mouthpiece of this device lies in front of the centerof the end of the shaft 22 which is turned toward it. The cutting offcontrivance 23 serves also for the severing of the thread, from thebobbin, stretched on the laying wheels 20 and 21.

The woolen threads required for making the chenille, which have beenvariously dyed, vhen the patterns were prepared, are led to eyeholes 32,placed beneath the table, from bobbins 31 standing on the floor underthe table 1. From there the threads pass to the guiding eyes fitted overthe table 1, and from thereagain, they pass on to the eyeholes 34, Figs.1 and 2, through which they are led to the needle eyes of the needles inthe thread changing device 13, Figs. 3' and 4. F rom there they are ledback again over the thread changing device 13 to the mouthpiece of thethread holder, not shown in F 1 and 2,. but lying in front of the centerof the shaft 22. See Figs. 1, 10, 11 and 23 26. In order to deal withthe variously dyed woolen threads that come from the different bobbins31, these threads are first led to the thread changing device 13, as hasalready been mentioned and as shown in detail in Figs. 3 and 4. Thisdevice consists of a guide-piece 37 firmly attached to a pedestal ortrestle 36, The guidepiece 37 has in it a number of vertical guide holescorresponding to the number of the woolen threads to be used and towardthe topit takes the form of a segment of a circle, cor responding to theradius of the thread guide wheel hereafter described. Parallel to theupper edge of the guide piece 37 and at some distance therefrom isfitted a hoop 38 which is firmly united with the pedestal 36 and theguide piece 37. The guide holes a d mit the needles 39 which rest witl rtheir points upon the usual pattern card, this pattern card being ledaround the roller 14 by means of the edge-pins '40 inserted in the edgesof the card. The length of the needles is so arranged that the end 4C1of each separate bent needle on the upper side reaches only to the hoop38. The movement of the needles is controlled by a bar 43 which movesvertically up and down on a suitable upright 4E2 which has also verticalguide holes in it. Each needle is enlarged above the lower bar 43 sothat a spiral spring slat, which surrounds the needle, has its upper endbearing against the guide frame 87, and

its low *1 end resting on the enlargement $5 of the needle 3S In thisway each needle is constantly pressed against the card 15 and alsoagainst the bar 43, when it is in its highest position, as shown in thedrawing. On the other hand, when the bar is lowered, any needle, whichcomes opposite a hole in the pattern card, can pass through the holedown into a groove (3 under the needle on the carrier roller l-Il whichturns forward step by step, while the other needles remain in theirraised position. The eye 35 of the lowered needle then draws down thethread coming from the corresponding bobbin, which is led over the hoop38, so that a hook of the thread guide wheel 29 coming under the bentends ll of the needles, in the direction of the dotted line A-B 3, cancatch the thread when drawn out in a loop and carry it farther on. Ifthe bar t?) is raised, the depressed needle will thereby be raisedagain, so that the card 15 can now be turned one step farther forward.The step by step movement of the carrier roller 14 and the rising andfalling of the lower bar 4L3, are efiected by two cam disks 4? and as,fastened on the shaft 7 see Figs. 1 and l. The cam disk 47 when rotatedbears against the one end of an angle lever 50 which is fitted so thatit will turn around a shaft 49,

while its other end is forked and clasps onv one side the bar t? whichmoves up and down on the vertical bolt 42. As the arm of the angle leverresting on the cam disk 4 .7 rises and falls under the action of asuitable spring, not shown in the drawing, the bar l3 also rises andfalls. The other cam disk 48 acts on a pin 51 which is constantlypressed against the disk 48 by means of a spring 52. On the free end ofthis pin there is a pawl 58 which works into a ratchet wheel connectedwith the roller 14 so that every time the pin 51 moves forward, theroller 1% will be turned one tooth. farther on.

As already mentioned, the thread loop formed by tl e descent of a needle39 is caught by one of the hooks of the thread guides 28, Fig. l, whichare fitted in sufiicient number on the thread guide wheel 29, and isthen led through between two pins on the first of the two laying wheels20 and 21, which have pins arranged around their circumferences, andwhich remain at rest during this motion of the thread guide wheel 29.The loop is then laid over the opposite pin on the second laying wheel.The two laying wheels 20 and 21 then move forward ove the spacecorresponding to two pins, so the next thread guide 28 can take up a newloop that has meanwhile been formed by the same or by some other threadon the thread changing apparatus 13. To facilitate this taking up andlaying down of the thr ad loop, the thread guide 28 constructed shown atFigs. 5 5 and (S. It consists of a tube 58 having a thickened collar 56which extends in a square or rectangular form some distance behind andis strengthened there by a steel. facing or nose-piece 57. The tube isfitted in a. box 59 on the thread carrier wheel 29, in such a way thatthe collar 5h; presses against the end 6l of the box so, under theaction of a spiral spring (5?). Between the collar 56 and the end (51 ofthe box 59 a suitable bufier ring 60 is inserted. In the end (51 of thebox 59 there is formed a suitable opening, preferably square. The spring(33 rests partly against the collar 56 and part y against a cap or cover(52 screwed on to the other end of the box. This cap has an opening inits center and the openings in the end and in the cap of the box serveto guide the tube 58 when it is moved longitiulinally. The squareend-guide prevents the tube from turning around. To the portion of thetube 58 which passes through the cap or cover 62 there is attached anarm (35 provided with a spring catch (34. In the tube 58 there is fittedav second tube 66 having a round head 67 which lies against the squareend of the tube 58.

The thread hook or catcher 69 is chamfered at one edge to facilitate adipping movement about a pivot or bolt 68, Figs. 5 and 5, in addition tothe revolution of this hook and pivot. The dipping presses the squareedge of the rear of the hook, adj acent to the chamfering, against thepressure stud operated by the spiral spring 72, and the slightinclination of the hook thus permitted releases the yarn over the secondpin of the wheel. Then the pressure stud and its spring 72 bring thehook back to erect position again by leverage upon the square corner ofthe rear 69* of the hook. This dipping of the hook with resultantcompression of the spring 72 occurs when strain is brought upon thethread. The inclination of the hook assists in the release of the threadafter it has been laid on the pin of the laying wheel, after which thehook returns to its erect position. On the other end of the tube 66,projecting from the end of the tube, there is a four-point ratchet wheel70, into which the catch 64 engages, also a four-point driving starwheel 71, and when this latter is turned the tube (:36 is also made torotate,

and wit-h it the hook or catch 69. The tube 66 also takes part in anymovement of the tube 58. The spiral spring 72 lies inside of the tube66. The work of the hook, namely to catch up the thread loop formed onthe thread chan ing appliance, to carry it over the thread laying wheels21 and 22 and then to lay it down, is now started and performed asfollows: When the wheel 29 turns, the thread guide or carrier-,aftertaking up the loop with its hook (S9 and leading it through between twopins 55 on the first laying wheel 20, strikes with its projecting nose57 against: a small. pedestal 73 (Figs. 1 and 1(3) which is litted onthe table 1 obliquely to the plane of the thread carrier wheel, so thatas the wheel 29 continues to turn, the tube 58 and consequently also thehook (39 are forced backward against the operation of the spiral spring(33. In this way the thread that has been caught up is gradually removedso far from the circumferential plane of the laying wheels 20 and 21that it can be carried over the opposite pin 55 on the second layingwheel 21. When the thread loop has been carried over the pin 55 inquestion, the end of the pedestal 73 is reached and the hook (59 isforced rapidly forward again by the action of the spring 63, being thuscaused to lay the loop over the particular pin: In order that thisoperation may be carried out without difficulty it is necessary toseparate from one another, to some extent, (Fig. 8) the two threads ofthe loop which lie close to one another when they were led off (Fig. 7).To effect this the hook 69 must be turned through an angle of 90degrees. This is done by the first of four striking pins 7 1 (Fig. 1)which are fastened on a holder in the form of a segment of a circle '75(Figs. 1 and 18) with the assistance of the ratchet gear (541, 70, thispin 74L causes the four-point star driving wheel 71 to turn through 90degrees. After the hook 69 has passed by the pin 55 on the second layingwheel 21, the driving star wheel 71 strikes against the second strikingpin 7s and that causes the hook to turn through a further angle of 90degrees. The hook (39 is thus caused to assume the position shown inFig. 9, in which it is possible for the pull on the thread to depressthe hook, which can be made to dip to such an extent that the threadloop can slip off it. lVhen it slips off the hook G9 the thread looplays itself around the corresponding pin 55 in the second laying wheel21. If the thread carrier wheel 29 be turned still farther the stardrivii'ig wheel 71 will strike against two' more striking pins 7% andthus the hook will be brought back into its original position.

The form of pedestal 73 (Fig. 1) is clearly shown in Fig. 16. The threadcarrier goes with its part- 5{' from a (l igs. 16 and 17) on the steelrail 13.4; of pedestal 73. By beveling the rail 131- to the pedestal 73,the thread.

carrier will be pressed back by rotation of the thread carrier wheel 29(Fig. 1) until it (the thread carrier) leaves at b (Fig. 17) the rail134 and will be returned to its first position, by means of its spring68 (Fig. 5). The position of the striking pins 7 1 (Fig. which arefastened on a holder in the form of a segment 75, are shown in Fig. 18.

It is necessary for the format-ion of a thread loop that both ends ofthe thread should be held firmly by some suitable means. For the one endthis is effected by the friction of the thread in running off thebobbin, and for the other end of the thread there is a thread holder,Figs. 10 and 11. This contrivance consists of two angle levers Ti; and77, each of which is caused by the pull of a spring 78 to bring one ofits arms to rest upon a cam disk 75) or 80. These 0* u disks arefastened on a shaft 81 which is driven by the chain wheel 30 (Figs. 1,19 and 20). The other arm of each jointed lever is connected in eachcase with a catcher or takeup 82, 83, which is fixed so that it willturn on the bracket 84. One end of each of the catchers 82, 83, isprovided with a catching head 85 (provided with a mouth piece not shown)the jaw 86 of which, in the course of the downward movement of thecatcher, bears on the bracket 84. The catchers work in such manner thatthere is always one of them holding down the threads. l'l hen one of thecatchers is down it does not rise again until the other catcher hasreached its lowest position and conseuentl y also presses down and holdsfast the threads. 87 shows a row of threads ready to be caught by thejaw of the upper catcher 82.

The bearing of the shaft 81 (Figs. 10 and 11) and the mechanism, whichis connected with it, are shown in Figs. 19 and 20. For receiving themechanism, which is shown in Figs. 10 and 11, the shaft 81 (Figs. 15)and 20) which is supported by the bearin 's 135 and 135, will be guidedalong the side of the table 1 to the middle of the laywheels 20 and 21.The relation of each with one another is clearly shown in Figs. 19 and20.

For the binding of the woolen threads laid upon the laying wheels 20 and21 and carried away from there, there are two sewing devices (Figs. 12and 13) with the requisite number of needles. Of these the second sewingdevice fastens and strengthens the seam made by the first and this givesthe pile threads a strong back also. The upper sewing mechanism of eachof these devices is fitted above the laying wheels 20 and 21, while theunder mechanism lies between them. To hold the upper mechanism inposition brackets 25, 26, are suitably secured to a pedestal 88 (Figs.12 and 13). These brackets 25, 26, are inclined to one another at aboutan angle of 45 degrees and on each of them there is fitted aneedle-frame 89 which slides up and down on special slides. This motionis effected by an eccentric 91 fitted on the shaft 8. The eccentric rodis connected with a shaft 9 1, by means of a crank 95 fitted at the sideand this connection is made either directly or by means of a connectingrod 92, the shaft 9a being carried in the bearing 93 fitted on thebracket. As the eccentric oscillates the needle-frame 89 is raised orlowered by means of two cranks 96 and two connecting links 97.

In the needle-frame 89 there are fitted a number of hooked pins 99 whichform the loop in the seaming thread. These pins correspond in number tothe needles 925, and immediately behind the hook a hole is providedthrough which the thread passes. On the back end of each of the hookedpins 99 there is secured a detachable disk 100 in order to make itpossible to fit a spiral spring 101 on the hooked pin 99. One end ofthis spiral spring 101 rests upon the disk 100 while the other end restsagainst the projecting inside edge of the guide hole in the needle-frame89. In this way the hooked pin 99 has always its hook pressed againstthe needle-frame 89. In order that the hooked pins 99 may move properlyduring the movement of the needle-frame, a rail or rod 102 is fixed onthe heel ends of the brackets 25, 26, transversely to the ends of thepins, and in such a way that the ends of the pins 99 slide along thisrod as the needle- :trame 89 moves. T iis makes it possible for thehooks of the pins 99 either to be moved away from the needle frame 89 orto be pressed against it during the movement ofthe frame, according tothe sectional form of the rod or rail 102. To insure proper sewing thereis also fitted a presser foot 103, fastened to two tubes 105 by means ofangle pie-es 10st. The tubes 10:) slide on guide pins 106 fastened inthe bracket of the needle frame 89. At their upper ends the tubes 105have each a collar 107 and on each of these collars a spiral spring 108surrounding the guide pin 106, exerts a downward pressure so that thetube 105, and consequently the presser-foot 103, are pressed against astitching plate 109. This stitching plate is attached by .ieans ofuprights 110 to a pedestal 111 fitted between the laying wheels 20 and21. In order to regulate the stroke of i the presser foot 103, two setpins 112 are fitted in the needle-frame 89, and each of these has acarrier 113 catching under the collar 107 of the tube 105. On the setpin 112 there is fitted a spiral spring 114; which is sufiicientlystrong to lift the presser foot 103. The set pin 112 lies under the setscrew 115, and when the latter is turned it can be held, along with thepresser foot 103, at any desired height, against the upward motion ofthe needle frame 89. The under portion of the sewing contrivanceconsists of a thread catcher 116 fitted with the same number of catchinghooks 117 as the needleframe 89 has needles. The catcher 116, which isfitted so that it will turn around and move along a tube 120 pushed overthe spindle 22 of the laying wheels 20, 21, is held in position bybearings 118, 119, and has on it a catching piece 121, on which slidesone arm of a bent lever 123, arranged to turn around a shaft 122, whilethe other arm of the lever can be moved to and fro by an eccentric 12 1fastened on the shaft 8. The mode in which the catcher 116 moves willtherefore depend principally on the shape of the catching piece 121, andthe catcher 116 may conse quently be made to move backward and forward,also sidewise, if a suitable form be given to the catching piece 121,and as a result of the pressure of the catcher 116 on the jointed lever123, this pressure being exerted by means of spiral springs not shown.The sewing threads are led from bobbins suitably arranged above thebrackets 25, 26, in the direction of the arrow O, and through the hookedpins 99 into the needles 98 attached to the needleframe 89. When theupper and lower sewing devices are put in motion the simple well-knownchain stitch seam is obtained which binds the threads stretched out onthe laying wheels 20, 21. lVhile in the arrangement shown a chain stitchseam is obtained other kinds of seams can be obtained if desired, byvarying the construction of the sewing devices. The threads when boundor attached together by means of sewing are then led to a suitablecutting off device 23 (see Fig. land Figs. 14 and 15), by turning thelaying wheels 20, 21, farther forward.

The cutting off device by which the loosely stretched series of threadsbrought along from the laying wheels can be cut into separate strips ofpile, preferably consists of fixed and movable knives 125 and 126, eachtwo of which form scissors. The fixed knives 125 are fitted alongsideone another in a knife box 127, at intervals corresponding to thedistances between the seams and in the space between each pair of seams.The moving knives 126 are each fastened by means of set screws toholders 128 said holders being fitted in a hollow rod or bar 130 whichcan be made to move to and fro by an eccentric 129 fitted on the shaft8. Each holder 128 is secured in place in the hollow rod or bar 130 bymeans of a set screw 160 catching in a groove 161 in the holder thearrangement being such that the holder can turn on its axis, a spiralspring 131, fixed at one end to a support and at the other end to theholder, being coiled around the holder as seen in Figs. 14 and 15 insuch manner that the moving knives 126 attached to the holder 128 areconstantly pressed sidewise against the fixed knives 125. The cuttingmotion of the movable knives is produced by the to and fro movement ofthe hollow rod or bar 130, on which the knife holders 128 are fastened.The separate strips of pile produced by this cutting oil mechanism arethen carried over a roller 132 to the material regulator 24 (Figs. 1 and4).

The regulating device for the material is formed of two rollers 24:which press one against the other, and between which the pile threadsare led, the pressure on the rollers holding them firmly. These rollersare so arranged that the upper one is moved forward to the same extentas the laying wheels 20 and 21 by means of a ratchet gear not shown inthe drawing and which is actuated by the shaft 8 and the pile threadsare thus kept under uniform tension from the laying wheels up to theregulator for the material, thereby making it possible to cut off theseries of threads by means of the cutting off mechanism alreadydescribed. From the regulating device the pile threads pass to anironing cylinder 133 which is heated by steam, and is so arranged thatit can be rotated at the same rate as the laying wheels 20, 21, by meansof ratchet gear not shown in the drawing. The cylinder 133 has on itssurface grooves into which the pile threads are pressed and in this waythe pile on both sides of the seam is ironed and then the completed pilethreads or chenille are led away over a roller to be wound up on reels.

The operation is as follows :The woolen threads coming from the bobbins31 are brought to the thread changing device 13. According to a certainseries, fixed by means of the pattern card 15, the woolen threads lie,through the sinking of the needles 39, in the path of thread guide 28,which latter rotates in a vertical plane with the thread guide wheel 29.The thread guide catches its thread, interlaces the bow of the samethrough two pins of the laying wheel 20 and puts the bow around theopposite pin of lay ing wheel 21. After the two laying wheels 20 and 21have turned for the distance of two pins, the next thread guide 28 comesinto operation and so on, so that, on the laying wheels 20 and 21 thereis a path of cross stretched threads. The thread path (so formed) goes,by the slowly suspended revolution of the laying wheels, to the firstsewing mechanism (by 25). The seams run parallel in the longitudinaldirection and the seams are kept equal distances from one another. Theseams will be fixed by means of the second sewing mechanism (by 26).After the thread path has passed the sewing arrangement it reaches thecutting off contrivance 23, where the thread path will be cut intosingle strips. These strips pass between the roller 24 of the materialregulating device to the steam heated ironing cylinder 133. The cylinder133 curls the thread ends and the strips finally reach a roller, wherethey are wound up on reels.

The thread comes from the bobbin 3 passing through eyeholes 32, 33, 34,which effect the guiding and stretching of the thread respectively afterwhich the thread passes into the sphere of activity of the thread guide28, in Fig. 1, or 69 in Figs. 5 to 9 respectively, passing theretothrough the needle eye 35 which ison the upper end of the reciprocatingneedle 39, Figs. 3 and *1. Further the thread runs over the hoop 38,

Figs. 3 and 4., (in the direction of the arrow in Fig. 1) to the deviceat 22, which holds fast the ends of the threads or always stretches thesame in consequence of its gripping action. Fig. 1 and Figs. 10 and 11.By this means the position of rest for all the threads underconsideration is shown see Fig. 23. In the sphere of activity A. B.(Fig. 3) of the thread guide 28 there will be a thread if the needle 39comes into the hole in the card-board and for this reason this oneneedle eye will be lower than the others and consequently below thecircle A. 13., Fig. 3. In the position of rest the needle eyes are abovethe thread guide circle A. B. (Fig. 3) while a sunken needle 39 standsbelow the same, so that the thread, going from the needle eye 35 to thehoop 38, is caught and taken along by the thread guide and indeed thethread will be held on or hung up on the pin of the laying wheel byreason of its passing between the two pins 55, Fig. 1, of the otherlaying wheel, thereby laying a double thread. It will be apparent thatthe thread which starts from the bobbin 31 is so guided that it goesfrom the needle eye 35 first through the space between two pins of theone laying wheel, afterward around the pin of the other-laying wheel andagain between the same pin space of the first laying wheel back to thecatch arrangement 22 (Fig. 1) where the end of the thread may still befound (Fig. 24;) Now this thread is caught and pulled through or laid uprespectively by the thread guide, whenever its needle 39, andconsequently, also the needle eye 35, falls in conformity with thepattern as this brings the thread in line with the path of movement ofthe wheel. This assumes that the laying wheel has progressed or movedforwardly a distance corresponding to the distance between two pinsbringing another pin in line. If this has not occurred, another needle39 and another portion of the thread controlled by it begin to act andthe first thread, whose two strands from the laying wheel to the catch22 and from the laying wheel to the eye 35 are now out of position, goesforward step by step with the laying wheel. That portion which goes tothe eye 35 is then again laid around the hoop 38 in the course of timeand is slowly unwound from the bobbin, until the laying wheels haveadvanced a half rotation and until the space between the pins 55 throughwhich the thread passes comes to the cutting off position, Figs. 1 and25. In the meantime, the gripping movement of the catches 82 and 83,Figs. 10 and 11, of the mechanism at 22 has again caught and clampedthat part of the thread, which is stretched from the laying wheel overthe hoop 38, so that now the cutting oil contrivance 23 may act withoutloosening the thread. The one part of the thread, from the laying wheelto the catch arrangement falls down as rubbish and the proper thread,which goes to the hoop 38 and through the eye to the bobbin 31, is oncemore in its original position of rest, which means that it goes from thebobbin through the eyes over the hoop 38 to the catch arrangement 22(Fig. l, 86 on Fig. 11 respectively). But the process described beforeis only necessary if a color or a needle and its thread, do not comeagain into action before the laying wheels have made over a halfrotation Fig. 25. But if it is the case that the same thread may beearlier worked oil, which is mostly the case, so also is the cutting oilof the same from the bobbin generally unnecessary. For example, if thelaying wheel has rotated with the thread (Fig. 24) so far that thisthread, for example, takes an inclined position from the laying wheel tothe hoop 38, its eye and its needle respectively being again lowered, soas to bring he thread near the thread guide, the former will be takenalong and, as described, laid around the laying wheels and now thethread, which goes to the higher placed pins of the laying wheels, liesegmentally on the same (Fig. 26). The threads, which lie segmentally onthe laying wheel, are rubbish and they tall down anton'iatically whenthey come into the sphere of action of the cutting oft contrivance 23.This action is alternatively repeated by each thread which comes from aneye so that consequently the end or the beginning of the threadrespectively is either guided forward by the laying wheel or held fastby the catch arrangement 22 (Fig. 1).
